When the protruding part 5 is used for holding, the heights of the multiple protruding parts 5 protruding from the second surface 22 can be the same. When the multiple protruding parts 5 are used for supporting, the multiple protruding parts 5 can be arranged at intervals along the height direction of the device, and the heights of the multiple protruding parts 5 protruding from the second surface 22 increase in sequence from the bottom to the top of the device, so that the side of the multiple protruding parts 5 away from the second surface 22 forms a supporting inclined surface, which is in contact with a bearing surface to support the electronic device. The bearing surface can be a flat surface or a concave-convex surface, etc.

[0045] In some embodiments, the number of protrusions 5 is two, the two protrusions 5 are arranged on the second surface 22 at intervals, and the side of the protrusion 5 away from the first surface 21 is an arc-shaped surface; the operation part 6 is arranged on the shell body 2 and is electrically connected with the first physical contact point 4, and the operation surface 61 of the operation part 6 is provided with an operation button 611, which can send a signal to the first physical contact point 4 under an external force.

[0046] In a possible case, as shown in Figure 2 、 Figure 7 、 Figure 8 The number of protrusions 5 is two, the two protrusions 5 can be arranged on the second surface 22 at intervals along the width direction of the electronic device, and the interval distance of the two protrusions 5 can be set according to the user's operation habit. In order to improve the comfort of the user, the side of the protrusion 5 away from the first surface 21 can be provided with an arc-shaped surface, which protrudes away from the second surface 22. In addition, in order to further improve the comfort of the user, the arc-shaped surface can include a plurality of arc-shaped grooves matched with the shape of the user's fingers, which facilitates the user to hold the protrusion 5. The shell 1 includes an operation part 6, which is arranged on the shell body 2 and can be arranged on the second surface 22 at intervals with the protrusion 5, or arranged on the operation part 6, which can be set according to the user's operation habit.

The user can apply different forces such as pressure or tension to the operation button 611 to trigger the operation button 611. For example, when the user presses a certain operation button 611, the circuit inside the operation part 6 will generate a specific electrical signal. The generated electrical signal is transmitted to the electronic device through the first physical contact point 4. For example, if the user presses the "A" key on the gamepad, the operation part 6 will generate an electrical signal indicating that the "A" key is pressed. After the electronic device receives this electrical signal, it will execute the corresponding operation according to the preset logic, such as triggering the corresponding action in the game.

[0047] In some embodiments, the operation surface 61 and the second surface 22 form an included angle.

[0048] In a possible case, as shown in Figure 8As shown, the operating surface 61 can be located on the side of the protrusion 5 near the top of the housing 1. To improve user comfort, the operating surface 61 can form an angle with the second surface 22. The angle can be any angle, set according to the user's operating habits, such as 30°, 40°, or 50°. When a user operates on a flat surface, the wrist usually needs to be bent at an unnatural angle, especially during prolonged use. This posture can lead to wrist fatigue or even pain. By designing the operating surface 61 at a certain angle, the wrist and fingers can be kept in a more natural and relaxed position, thereby reducing pressure on the wrist.

The carrier provides a physical platform for mounting and fixing various electronic components, such as microprocessors, sensors, resistors, capacitors, connectors, etc. The carrier connects the various electronic components through internal conductive paths (such as copper foil lines) to form a complete circuit, realizing electrical connections between the electronic components. Certain specific locations on the carrier, such as connectors or contacts, are electrically connected to a third physical contact point 71 on the device body 7. Through this electrical connection, the electronic components on the carrier can transmit data and power to the housing 1. The third physical contact point 71 can be an array of multiple metal pins or a connector composed of springs and metal pins, capable of maintaining good electrical contact under certain pressure. The housing body 2 can be detachably connected to the device body 7 via bolts, snap-fit ​​structures, or other connecting components.

Through the design of the first connecting part and the first physical contact point 4, the use of multiple power lines and signal lines in the traditional device is eliminated, and additional power lines and signal lines are no longer needed. The weight of the overall device is reduced, and the portability and use comfort are improved. In addition, the data transmission realized through the first physical contact point 4 avoids the delay problem in Bluetooth transmission, and provides more stable and instant data exchange.

[0052] In some embodiments, a first functional component is further included, which comprises a second connecting part for fixed connection with the shell body 2 or the device body 7, and a second physical contact point arranged on the first functional component.

[0053] In a possible case, the first functional component is an independent component with specific functions, such as a cooling fan 8, an additional battery, a camera enhancement module, etc. The first functional component comprises a second connecting part, which can be a buckle, a magnetic attraction structure, etc. The first functional component is fixedly connected with the device body 7 through the second connecting part. The first functional component is provided with a second physical contact point, which can be a plurality of metal needle arrays or a connector composed of a spring and a metal needle, capable of maintaining good electrical contact under a certain pressure. When the first functional component is fixedly connected with the shell body 2 through the second connecting part, the second physical contact point is aligned with and contacts the first physical contact point 4 on the shell body 2, realizing data transmission and power transmission between the first functional component and the shell body 1. When the first functional component is fixedly connected with the device body 7 through the second connecting part, the second physical contact point is aligned with and contacts the third physical contact point 71 on the device body 7, realizing data transmission and power transmission between the first functional component and the carrier. The first functional component not only provides specific functions, but also realizes efficient connection with the shell body 2 or the device body 7 through the second connecting part and the second physical contact point, thereby improving the use experience of users.

[0054] In some embodiments, the number of the first physical contact points 4 and the third physical contact points 71 is multiple, the multiple first physical contact points 4 and the multiple third physical contact points 71 are one-to-one corresponding and electrically connected; the number of the first functional components is multiple, the second physical contact points of the multiple first functional components are one-to-one corresponding to the multiple first physical contact points 4 and are used for electrically connecting with the first physical contact points 4; and / or the second physical contact points of the multiple first functional components are one-to-one corresponding to the multiple third physical contact points 71 and are used for electrically connecting with the device body 7.

[0055] In a possible case, a plurality of first physical contact points 4 can be arranged on the shell body 2, and a plurality of third physical contact points 71 corresponding to the first physical contact points 4 can be arranged on the device body 7, when the shell body 2 is fixedly connected to the device body 7, the first physical contact points 4 are in contact with and electrically connected to the third physical contact points 71. In addition, the number of the first functional components can be multiple, and each first functional component has a second physical contact point. When the shell body 2 is fixedly connected to the device body 7, the second physical contact point of the first functional component can correspond to one of the first physical contact points 4 on the shell body 2 and be electrically connected, so as to realize the power transmission or signal transmission between the first functional component and the shell body 2 or realize the power transmission or signal transmission between the first functional component and the device body 7 through the first contact point; or the second physical contact point of the first functional component can be directly in contact with and electrically connected to the third physical contact point 71, so as to realize the power transmission or signal transmission between the first functional component and the device body 7. When the shell body 2 is fixedly connected to the device body 7, multiple first functional components can be connected to the shell body 2 at the same time, or multiple first functional components can also be directly arranged on the device body 7. The functions of the multiple first functional components can be the same or different, for example, multiple heat dissipation fans 8 with the same function are connected to the shell body 2, which simultaneously dissipate heat for the shell body 2 and the device body 7, or at least one of the multiple first functional components is a camera, at least one is a heat dissipation fan 8, and at least one is an additional battery, wherein the camera can be used for shooting or video call; the heat dissipation fan 8 is used for cooling; and the additional battery provides longer endurance for the device. Such a structure can enable the user to flexibly select and configure additional first functional components according to personal needs, so as to make the device system more personalized and efficient. Since the shell body 2, the device body 7 and the first functional components are electrically connected through the physical contact points, not only the compactness and portability of the device structure can be maintained, but also the user experience and the maintainability of the product can be improved.

[0056] In some embodiments, the first functional component is a fan 8, which includes: a fan body 81 having a receiving cavity 811, and the receiving cavity 811 has an opening; a fan blade assembly 82 arranged in the receiving cavity 811; a protective cover 9 corresponding to the opening and detachably connected to the fan body 81, and the first surface 91 of the protective cover 9 facing away from the fan body 81 is an arc surface and the first surface 91 is provided with a plurality of heat dissipation holes 911.

[0057] In a possible case, as shown in Figures 9-11 The fan body 81 is the main structural part of the fan 8, and its interior contains a receiving cavity 811. The receiving cavity 811 is provided with an opening to facilitate the entry and exit of air, achieving heat exchange. The fan blade assembly 82 is arranged in the receiving cavity 811 of the fan body 81, which can be driven to rotate by a motor, generating airflow to facilitate air flow and carry away heat. The protective cover 9 is located at the opening of the fan body 81 and can be detachably connected to the fan body 81 through bolt connections, buckles or other connection structures. The protective cover 9 can prevent external objects from entering the interior of the fan 8, avoiding damage or failure caused by foreign objects blocking the fan blades. The first surface 91 of the protective cover 9 facing away from the fan body 81 is an arc surface protruding away from the fan body 81. The arc surface can guide the airflow to flow more smoothly, reducing the occurrence of turbulence, and help to direct the airflow to a specific direction, making the airflow more concentrated and directional. In addition, the arc surface can also help the airflow to diffuse better, especially at the outlet of the fan 8. This can make the airflow cover a larger area, thus cooling the entire space or surface more evenly, rather than just concentrating in a small area directly in front of the fan 8. The interaction between the airflow generated by the rotation of the fan blades of the fan 8 and the protective cover 9 of the fan 8 can also produce noise. The arc surface can help smooth this interaction and reduce the "whistling" sound produced when the blades cut through the air. The shape of the heat dissipation holes 911 on the first surface 91 can be any shape, such as circular, rectangular or polygonal, etc.

[0058] In some embodiments, further comprising: an extension 10 connected to the outer peripheral side wall of the fan body 81 and arranged offset from the opening; a third connecting part arranged on the fan body 81 or the extension 10 for fixed connection with the shell body 2 or the device body 7; a fourth physical contact point 12 arranged on the extension 10; wherein, in the case of fixed connection of the third connecting part with the shell body 2, the fourth physical contact point 12 is used for electrical connection with the first physical contact point 4; in the case of fixed connection of the third connecting part with the device body 7, the fourth physical contact point 12 is used for electrical connection with the third physical contact point 71.

[0059] In a possible case, as shown in Figures 9-10As shown, the outer peripheral wall of the fan body 81 is provided with an extension 10 for providing additional space for the fan 8 to install other components, avoiding occupying the air flow passage of the fan body 81. The third connecting part is used for fixedly connecting the fan body 81 with the shell body 2 or the device body 7, and can be a magnetic attraction structure, a buckle structure, etc. The third connecting part can be arranged on the side of the fan body 81 opposite to the air outlet, and in order to avoid the third connecting part affecting the heat dissipation of the fan 8, the third connecting part can be arranged on the extension 10. The fourth physical contact point 12 of the fan 8 is arranged on the extension 10, and the fourth physical contact point 12 can be an array of multiple metal pins, or a connector composed of a spring and a metal pin, which can maintain good electrical contact under a certain pressure.
